Electrospun nanofibers for cancer diagnosis and therapy

Abstract: The advent of nanotechnology has provided unprecedented opportunities for nanomedicine. Electrospun nanofibers have some astounding features such as high loading capacity, extremely large surface area and porosity, high encapsulation efficiency, ease of modification, combination of diverse therapies, low cost and great benefits. These remarkable structure-dependent properties have far reaching application potential in cancer diagnosis and therapy such as ultra-sensitive sensing systems for point-of-care cancer detection, targeted cancer cell capture, and functional and smart anticancer drug delivery systems. This review summarizes the principal mechanism of electrospun nanofibers and a variety of modified electrospun nanofibers, illustrates their application in biosensors for cancer detection, and enumerates their application in implantable drug delivery for cancer therapy.

Mechanical and electronic properties of superhard Re B 2

Abstract: Considering the effect of spin-orbit coupling, we have studied the equation of state, elastic properties, and the electronic structures of $\mathrm{Re}{\mathrm{B}}_{2}$ by first-principles plane-wave basis pseudopotential calculations. Our calculated results show that $\mathrm{Re}{\mathrm{B}}_{2}$ has high bulk modulus $(356\phantom{\rule{0.3em}{0ex}}\mathrm{GPa})$, large shear modulus $(293\phantom{\rule{0.3em}{0ex}}\mathrm{GPa})$, and great elastic constant ${c}_{44}$ $(284\phantom{\rule{0.3em}{0ex}}\mathrm{GPa})$, and thus support that $\mathrm{Re}{\mathrm{B}}_{2}$ is ultraincompressible and a potentially superhard material. Besides the compact crystal structure, the electronic mechanisms of its hardness can be understood from the highly directional covalent bonds and the optimal filling of the bonding states.

Advances in graphene-based semiconductor photocatalysts for solar energy conversion: fundamentals and materials engineering

Abstract: Graphene-based semiconductor photocatalysis has been regarded as a promising technology for solar energy storage and conversion. In this review, we summarized recent developments of graphene-based photocatalysts, including preparation of graphene-based photocatalysts, typical key advances in the understanding of graphene functions for photocatalytic activity enhancement and methodologies to regulate the electron transfer efficiency in graphene-based composite photocatalysts, by which we hope to offer enriched information to harvest the utmost fascinating properties of graphene as a platform to construct efficient graphene-based composite photocatalysts for solar-to-energy conversion.
